Description

Canon EF to BMPCC Speed BoosterTM adapters designed exclusively for the Blackmagic Pocket Cinema Camera (BMPCC). Note that this new 0.58x Speed Booster will only attach to BMPCC equipped with a Micro-4/3 mount. They cannot be attached to standard Micro 4/3 cameras (cannot be attached to GH4, GH3, GH2 and GH1 body).

The new 0.58x Speed Booster reduces the crop factor of the BMPCC from 3.02x to 1.75x and produces the largest aperture optics currently available, with a maximum output aperture of f/0.74.

Table of compatibility and resulting crop factors with different SpeedBoosterTM:

Some improperly-made M42 screw mount adapters may short the electronic contacts of the Speed Booster and cause damage to the Speed Booster and/or camera body.

Many manual focus lenses (e.g. OM 28/2.8, OM 50/1.8, Leica R 15/3.5) have rear protrusions (spikes, levers, other appendages) which would damage the optics and/or housing of Speed BoosterTM They need to be modified before they can be safely used on Speed BoosterTM Check and make sure there are no rear protrusions from the adapter/lens combination before using on Speed Booster. Scratches and damages caused by rear protrusions on Speed BoosterTMare not covered by warranty.

This Speed Booster is NOT fully compatible with GH4 or other MFT camera. This is use only with BMPCC. When Speed Booster® is used with other MFT camera, it may cause damage on the camera.
